Catherine (
Marg Helgenberger) investigates when the production of a "faked" snuff film results in the far-from-fake stabbing death of a young woman. Or did a murder actually occur? Clues are either vague or nonexistent, and Catherine finds herself running down a multitude of blind alleys. Meanwhile, Grissom (William L. Petersen) pieces together the evidence when an abandoned aluminum toolbox yields a human skeleton -- infested with imported fire ants. ~ Hal Erickson, All Movie Guide
